PNEUM ATIC CASH-TRANSMITTER.

SPECIFICATION formingpart of Letters Patent No. 279,090, dated June 5, 1883.

' Application filed February 23,1883. (No model.)

To all whom it may concern.-

Be it known that I, HENRY GAZAILLE, a subject of Great Britain, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Pneumatic Gash-Transmitters5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable IO others skilled in the art to which it appcrtains 5 invention;

- receiver, while Fig. 4 is asection on line 1 2,

counter A,

to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to devices for transmit-ting cash from a salesman to the cashier, and vice versa, in stores and other business establishments.

My invention consists in the employment of 20 a tube of uniform diameter containing aclosely-fitting cash-box adapted to traverse it, one end of such tube being open and terminating at the cashiers desk and its opposite end closed and terminating at a point convenient 2 5 of access to the salesman, and the combination,

with thislatter and of the tube, of an air-pump or its equivalent for inducing a current of air through said t-ubein either direct-ion, and the further combination, with the tube and pump,

0 of a signal adapted to be operated by the cash-- 0 sent ajportion of a counter in a dry-goods establishment or other place of business employing salesmen and a cashier. I

B represents a tube of uniform diameter, one end, 0, of which terminates beneath the convenient of access to a salesman,

while the opposite end, D, of I the tube terminates at the cashiers desk. In one end of the tube B an opening, a, is made to permit of insertion of the cash-box, such opening being covered by a door, 0,10 permit of its being tightly closed.

E represents a straight cylinder, situated beneath the counter A, and connecting at its lower end with the extremity of the tube B, this cylinder containing closely-fitting plunger, F, the rod G of which rises through the cap of the cylinder and a stuffing-box applied to;such cap, and preferably has upon its upper end a knob, d, to receive thehand of the operator; or the top of the cylinder may be open, as shown in Fig. 2 of the drawings.

H represents a wire stretched alongside the tube B, one end of which wire terminates at the cashiers desk and the other connected to an electric bell or other signal in immediate proximity to the opposite end of said tube B- that is, the place occupied by the salesman. This signal may be an ordinary bell or gong operated mechanically by the cashier; but I prefer to employ an electric wire and gong'to beoperated from the cashiers desk.

The object of the signal is to enable the cashier to notify the salesman when his change is ready for him. 7

The cash box or carrier is a cylinder, I, of considerable less diameter than the tube, one end or head, 0, of such box being of wood of a size to somewhat loosely fill the interior of the tube. The opposite end of the box I is provided with a head, f, of felt or other elastic or semi-elastic material, which shall closely fill the interior of the tube and prevent leakage of any appreciable amount of air between the two.

The object'in making the body of the cashbox of considerably less diameter than the tube is to permit it to travel about curves in such tubes, its two heads forming its bearingpoints. v

In the operation of this device the salesman deposits his cash and check within the box I and places the latter, wood end first, within the tube B, through the opening a, and tightly closes the door of such opening. The object of putting the loosely-fitting wood end first into the tube is to have the tightly-fitting elastic material on the rear end prevent the air from passing by it, and thereby propel the cashbox to its destination. He then pushes down the plunger F with a quick movement, which drives a puff of air rapidly through the tube B, carrying the caslrbox before it to the cashiers desk, it being understood that the end of the tube nearest the cashiers desk is open to the atmosphere. The cashier now removes the box by way of the opening 1), makes the requisite change, and inserts the box in the end of the tube, wood end first, also by way of such opening, thereby hermetically closing the tube at, this end. The cashier now presses or pulls the knob of the wire H, thereby notifying the salesman that his change is ready. The salesman thereupon pulls up the piston or plunger F and exhausts the air from the tube in front of the cash-box, the result being that the tendency to a yacuum in the tube induces a current of air through the latter in a direction opposite to that first described, and the cashbox, with its contents, is returned to the salesman, who removes it.

It will be seen thata considerable stretch, B, ot' the tube B interven es between the stoppin place 1? of the cash-box and the air cylinder or pump E. The object of this is to provide a reservoir to store up a quantity of air to be expelled through the tube with the next dc scent of the plunger F.

I have provided the receivingbox for the salesman with a pad, 71, of elastic material, to

be placed in each end of the tube B to overcome the inertia of the cash-box. I have also made this chamber somewhat longer than the cash-box, so that the tightly-fitting rear end of said box emerging from the tube B allows the air under atmospheric pressure to rush by and through the perforated partition y, and the box stops at once, as the equilibrium is restored the instant the elastic material on the head f emerges from the end of the tube B at either end.

1. The tube B, branch B, pump E, and box I, constructed and arranged as herein explained, whereby a reservoir is provided be tween the stoppingplace of the cash-box and the pump to store up air, sul'istantially as setforth.

2. The CtlSll1)OX constructed as herein described, with its body of less diameter than its heads, for the purposes stated, and with its front head loosely fitting the tube, while its rear end is made of felt, and closely fills the same, substantially as described.

3. The tube constructed'with the opening 7) to permit of insertion of and removal from the tube of the cash-box, the cover 0 to tightly close such opening, the extension B of the tube beyond the stopping-place ofthe cash -box, and the perforated partition between the two, subvstantially as stated.

In testimony whereof I at'fix my signature in presence of two witnesses.
